Here's why:

* Kinetic energy is the energy of motion. The faster particles move, the more kinetic energy they have.

* Temperature is a measure of the average kinetic energy of the particles within an object.

* Higher temperature means the particles are moving faster on average, which means they have higher kinetic energy.

This relationship explains why things feel hotter when they have a higher temperature. The faster-moving particles collide with our skin more forcefully, transferring more energy and creating the sensation of heat.
